Free Online Scientific Calculator 2025

About Scientific Calculator

Our scientific calculator is a powerful tool designed for students, engineers, scientists, and anyone who needs to perform complex mathematical calculations. It offers a wide range of functions beyond basic arithmetic, including:

• Trigonometric Functions: Calculate sine, cosine, tangent, and their inverses in both degrees and radians.
• Logarithmic Functions: Compute natural logarithms (ln) and base-10 logarithms (log).
• Exponential Functions: Calculate powers, square roots, and exponential values.
• Memory Functions: Store and recall values for complex calculations.
• Constants: Access mathematical constants like π (pi) and e.

How to Use the Scientific Calculator

Using our scientific calculator is straightforward:

1. Enter numbers using the number pad.
2. Use the function buttons for specialized calculations.
3. Toggle between degrees (DEG) and radians (RAD) for trigonometric functions.
4. View your calculation history in the History tab.
5. Use memory functions (MS, MR, MC, M+) for complex multi-step calculations.
